Upon these brackets are supported and so that the stop-arm i will automatically drop secured the independent flexible tubes D. into engagement with the shoulder g of the With one end of each tube is connected the cut-off block G when said block is pressed o 40 pipe e, which extends upwardly through the down. As long as this engagement continues top of box A, and each pipe has connected the block is held down; but upon dropping a with its upper end a hearing-tube E, which is suitable coin-into the passage II through the of the usual style and hangs down in front of slot a, said coin in its downward course box A. The other end of the tubes D is carthrough the chute will come in contact with 5 ried baekwardly through the board C, and the projecting end of trigger-arm 2", and each has connected with it a tubular arm f thereby move said arm. This rocks shaft I of a horizontal main sound-pipe F, which exand removes its stop-arm i from engagement tends along and is supported by the back of with the shoulder g of block G, and said block, board C, so that said pipe F is connected with being free, isforced upwardlybytheexpansion I00 all the flexible tubes D. From the main pipe of tube D, due to its own elasticity. Thus the F extends upwardly a pipe f, which passes tube D is opened for the passage of sound.

This vertical movement of the cutoff block G is made to subserve another purpose, to wit, the closing of the electric1notor circuit by which the motor is driven and the phonegraph set in operation.

It is unnecessary herein to show the motor by which the phonograph is operated, and it is sutficicnt to say that a motor-circuit, of which X are the wires, is established, having such a course that it is opened and closed by the contact-springsJ and J. The springs J are secured to the face of board 0, and the springs are secured to and carried by the cut-01f blocks G. hen the blocks are down to their normal position, the springs J and J are out of contact and the motorcircuit is open and all the parts are inactive; but upon the upward movementof the block G the spring J is brought into electrical contact with the spring J, whereby the circuit is closed, the motor driven, and the phonograph set in operation. The operation, therefore, up to this point is as follows: Upon dropping the proper coin into the slot at and passage 1] the trigger mechanism is affected to relieve the block G, which thereupon rises, opening the tube D, and at the same time closing the motor-eireuit, whereby the phonograph is operated, and it can be heard by the visitor who applies to his ears the hearing-tube E.

The object of providing a series of slots a and coin-chutes II and the separate parts relating to each is to permit more than one person at a time to hear the phonograph; but it will be observed that the ar angement is such that each person desiring to hear must deposit his coin and cannot take advantage of the generosity of another. This results from the independent tubes D, which, though all are connected with the main pipe F, each has its own hearingtube E, and each has its own cutoff block G. Therefore, when one visitor deposits his coin and applies the hearing-tube E to his ears, he alone can hear, for his coin operates only the cutoff block of his own hearing-tube connections, the other blocks remaining in normal position and cutting off the other tubes 1) and their hearing-tubes; but when a second person deposits a coin in another slot he too can hear.

In order to return the cut-off blocks to their normal position and press them down upon the tubesD at the end of the operation, there is a swinging presser-bar K, suspended by pivoted links it along the face of the board 0. The lower edge of this bar is adapted by the swinging movement to be brought down upon the tops of the cut-off blocks and to force them down on the flexible tubes 1). This movement of the baris accomplished by the following mechanism. Pivoted in asuitable bracket to, under the top of box A, is abell-crank or bent lever L, the upper arm of which projects through an elongated slot in the box-top and is slotted over the end of the arm 1:, projecting rcarwardly from the spectacle-frame of-the phonograph. Pivoted to the end of the lower arm of lever L is a pawl Y, which. is eontrolled by a spring 1, and has on its end a small tooth Z The lower arm of lever L also carries an adjustable stopscrew Z, the point of which is directed against the pawl Z. Mounted in the box A is a rockshaft M, one end of which carries a crank in, the lower end of which engages a pin 7; on the presser-bar K. The rock-shaft also carries a rocker-arm m, having a notch m in its end, which is adapted to receive the tooth Z of the pawl I. Now, as the spectacle-frame of the phonograph moves on its forward course its arm 11 carries the lever L over with it, and the pawl Zgraduallymoves down until at the end of the operation its tooth Z engages the notch m of the rocker-arm on. Then as the spectacle-frame and its arm move back again the lever L is returned, and its pawl, holding to its engagement with arm m, rocks shaft M, which movement, through the crank m on the end of the shaft, swings the presscr-bar K down into contact with the cutoff blocks G, thereby forcingthem down upon the flexible tubes D, where they are held by the stop-arm t' of shaft 1; but as said blocks must be relieved of the bar for a repetition of the operation, the stop-screw Z comes into action as follows The pawl I, being pivoted to the lever L, hangs freely therefrom and remains in its engagement by the power of its spring Z; but as said pawl is resisted by its engagement, it lags behind sufficiently on its pivot to allow the stopscrew to catch up and come into contact with it, and when this occurs the pawl is forced from its engagement, thereby releasing the rock shaft M. Thereupon to return the presser-bar K, a spring Z1 attached to one on d of the bar, immediately draws it back, and thereby relieves the cut-off blocks. As, however, when the cut-off blocks are pressed down the motor-circuit is broken by the separation of the contact-springs J and J, it follows that some provision must be made for keeping the circuit closed and operative in order to effect the return of the parts. This is effected by the contact-springs N and N, which are let into the circuit. The spring N is on the board C and the spring N is on the end of the presscr-bar K. N ow, when the bar is being forced down by the mechanism heretofore described, and thereby causing the separation of the contacts J' and J, the contactspring N on the end of the bar immediately comes in contact with spring N, thereby keeping the circuit closed, so as to continue the operation to effect. the return of the phonograph-spectacle, and the circuit is thus kept closed until it is broken by the retraction of the bar under the power of its spring 7;, whereupon the entire mechanism is inactive.

In order to automatically effect the return of; the spectacle of the phonograph, there is the following mechanism: To fully linden stand this some of the parts of the phonograph will now have to be described. The

IIO

spectacle p and its connected parts are mounted pivotally upon the back rod 19 so that they can travel on said rod, and also swing sufficiently to be thrown down into contact with or up away from the cylinder, according as they are traveling forwardly or returning. The traveling spectacle frame carries a nut-arm 19 which has a nut at 10 which engages the well-known fine-threaded feed-screw p of the main shaft, whereby the parts are fed forwardly. The nut-arm extends across the machine and carries in its outer end the depending return-nut p, which, when the arm is raised, is adapted to come up into engagement with the return-screw p Along the front of the machine extends the jig-back rail 19 These parts are all common to the phonograph. Now, to the front of the jig-back rail 19 is attached a guide-bar 0, having a top flange 0, which projects inwardly over the edge of the rail. This flange is broken away in two places to form the openings 0' and 0 To the inner side of the guidebar, below its flange and sufficiently separated therefrom to-leave a space, is secured a spring Q, the free end of which curves upwardly and projects through and above the opening 0' in flange 0. A similar spring R is secured. to the guide-bar at its first end and projects upward and beyond said end.

Projecting outwardly from the return-nut p is a foot q, the point of which is adapted to play above and below the flange o alternately, and secured to the spectacle-frame is a similar foot 1', adapted likewise to travel above and below flange 0. Now upon the forward travel of the spectacle and the nut-arm the feet q and 1' both travel under the flange 0, for they are then depressed by the spectacle, being in contact with the cylinder and the nut-arm being down, whereby its feed-nut p is in engagement with the feed-screw and its returnnut is out of engagement below the returnscrew; but when the limit of forward travel is reached the foot 4', moving under the flange 0, passes near the end just above spring B, so that as it passes from under the end of the flange 0, depressing said spring in so doing, the latter, when the foot is free of the flange, immediately throws the foot up to a plane above the flange, and thereby raises the spectacle out of contact with the cylinder in order to allow it to return without touching it. Immediately after this throwing up of the foot 7' the foot q is similarly thrown up by the spring Q, through the opening 0', to a plane above the flange o. This throws the nut-arm up, whereby its feed-nut is disengaged and its return-nut is forced to engagement with the return-screw. Thereupon the parts move on their return, the feet 0" and q traveling above flangeo until when the former reaches opening 0 in the flange and thelatter reaches the end of the flange they both drop down again and return the parts to position for forward movement again. The springs Q and R are in the nature .of cams, but their action is quicker. The guide-bar O is adj ustably secured to the jig-back rail by means of slots and pins 0 whereby its position may be regulated to properly time the action of its springs Q and R. It will be seen that this automatic return of the spectacle may be made use of in other connections than coin-actuated onesfor example, where it is desirable to exhibit a constantly-operating phonograph, one which will repeat itself and serve for advertising purposes. In this connection the automatic return of the spectacle is important and essential.
